The characteristics of the pharyngeal bones and their teeth in Korean Cyprinids fishes, as a rule, are summarized as follow : 1. The materials 13 genera and 17 species from Nak Dong River. 2. Breadth of bone about 2.8(Cyprinus carpio) to 4.9(Culter brevicauda) in bone length. Length of bone about 8.5(Carassius carassius ) to 20.2 (Pseudogobio esocinus ) in body length. Breadth of pitted surface about 66%(Carassius carassius) to 85%(Acanthorhodeus asmussi ) of breadth of bone. 3. The position and distinct ratio of anterior angle correlated. 4.

Water Pollution of Gwangju Stream was examined for four months from 22 March 1981 to 7 June, 1981. For checking the water pollution, 6 sampling positions were selected 5 from main stream. We assumed that the water pollution of Gwangju stream was due to the organic materials, which came from the domestic sewage. The apparatus for this test were pH meter (Orion model 301), Dissolved Oxygen & Temperature meter(Delta model 1010). The results we obtained are as follows: 1. The average range for mid-stream(sp. 3, 4) was 3. 10~2.73ppm of Dissolved Oxygen(DO), 80.23~102.95ppm of Biochemical Oxygen Demand (BOD), 195. 10~165.90ppm of Suspended Solid (SS), 6.6~6.7 of pH. 2. The plankton identification in this survey period showed Cyanophyceae is 4 genera 5 species, Bacillariophycea 11 genera 14 species, Chlorophyceae 8 genera 15 species and Zooplankton 6 genera 7 species: total 29 genera 41 species. 3. To appear dominant plankton in polluted water, there were Paramecium, Euglena and Oscillatoria. 4. The results of biological water analysis were as follows: st. 1 was B-mesosaprobic to oligosaprobic, but st. 4 and st. 5 at stream in the midtown area seemed to be polysaprobic.

Objectives : The plans can be used for medicinal purposes among Alismatales in korea and examined their effects and distributions. Methods : The examined herbalogical books and research papers which published at home and abroad. Results : 1. There were totaled to 15 genera and 45 species in Alismatales in Korea and among them medicinal plants are 8 genera, 17 species, some 38% in total. 2. Potamogeton genus is main kind enough that it has 14 species among 45 species in the Alismatales , of which medicinal plants are 6 species. 3. The herb is the main medicinal parts of medicinal plants in the Alismatales which is used in 14 species. 4. According to nature and flavor of medicinal plants in the Alismatales , they were classified into cool 8 species; sweet taste 10 in the order. 5. According to meridian propism of medicinal plants in the Alismatales, they were classified into liver meridian 8 species. 6. According to the properties and principal curative action, they were classified into drugs for antifebrile 12 species, drugs for detoxicant 11 , drugs for drain damp 9 in the order. 7. It was noticed that every medicinal plant in the Alismatales is nontoxic. Conclusion : There were totaled to 15 genera and 45 species in Alismatales in Korea and among them medicinal plants are 8 genera, 17 species, some 38% in total.

Objectives : For the purpose of developing Korean herbalogy of the plants belonging to Polypodiaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. The results of this study are as follows : Methods : The examined herbalogical books and research papers which published at home and abroad. Results : 1. There are totaled to 8 genera and 24 species in Polypodiaceae in Korea and among them medicinal plants are 7 genera, 11 species, some 46% in total. 2. Pyrrosia genus is main kind enough that it has 5 species among 24 species in Polypodiaceae, of which medicinal plants are 3 species. 3. The herb is the main medicinal parts if medicinal plants in the Polypodiaceae, which is used in 9 species. 4. According to nature and flavor of medicinal plants in the Polypodiaceae, they were classified into cool 9 species, and cold 5; sweet taste 10 and bitter taste 8 in the order. 5.

Objective : For the purpose of developing Korean herbalogy of the plants to Aspleniaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : The examined herbalogical books and research paper which published at home and abroad. Results : 1. There are 2 genera and 21 species in Aspleniaceae in Korea and among them medicinal plants are 2 genera and 10 species, some 48% in total. 2. Asplenium genus is a main kind in that it has 20 species among 21 species in Aspleniaceae of which medicinal plants are 9 species. 3. The Herb play medicinal parts if most plants in the Aspleniaceae have the effect of a medicine, the 10 species of which are used for medical care. 4. According to nature and flavor of medicinal plants in the Aspleniaceae, the cold medicinal plants and the bitter medicinal plants take the highest number of them 5. According to the properties and principal curative action, they were classified into drugs for hemostatic 10 species, drugs for clearing away heat 8 species, drugs for detoxification 7 species respectively. 6. None of the species of Aspleniaceae have been found to be toxic. Conclusions : There are totaled to 2 genera and 21 species in Aspleniaceae in Korea and among them medicinal plants are 2 genera and 10 species some 48% in total.

Phytophagous insects were surveyed for biological control of weeds in the southern part of korea from April 20 to July 31, 1987. Phytophagous coleopteran insects representing 12 families, 52 genera and 61 species, hemipteran insects 7 families, 18 genera and 20 species, homopteran insects 4 families, 16 genera and 21 species, hymenopteran insects 2 families, 2 genera and 3 species, and orthopteran 2 familes, 6 genera and 6 species were recorded from 58 weeds. Some chrysomelids and orthopteran insects were potential agents for biological control of weeds.

The trend in naming genera based almost exclusively on molecular data, and not on morphological diagnostic characters, is increasing. In bifurcating phylogenetic trees generic cut-offs are arbitrary, but at the bare minimum nomenclatural changes should be supported by multiple phylogenetic methodologies using appropriate models for all the various gene partitions, strong support with all branch support methods, and should also result in adding to our knowledge of the interrelationships of taxa. We believe that a recent taxonomic treatment of the genus Pyropia (Yang et al. 2020) into several genera is unwarranted. We reanalysed the data presented in the recent article, using additional phylogenetic methods. Our results show that many of the newly established genera are not well supported by all methods, and the new circumscription of the genus Pyropia renders it unsupported. We also tested additional outgroups, which were previously suggested as sister to Pyropia, but this did not substantially change our conclusions. These generic nomenclatural changes of the previously strongly supported genus Pyropia, do not shed light on the evolution of this group and have serious consequences in these commercially important algae, that are also governed by a plethora of regulation and by-laws that now need to be amended. We suggest that the over-splitting of groups based only on poorly produced and modestly supported phylogenies should not be accepted and that the genus Pyropia sensu Sutherland et al. (2011) be restored.

A new genus and two new species of Bathynellacea are described from California in USA. Califobathynella, a new genus, belongs to the subfamily Leptobathynellinae, and is closely related to the genera Parvulobathynella and Leptobathynella but differs from them with respect to labrum, maxillule, maxilla, and male thoracopod VIII. Based on the detailed structure of mouthparts, the phylogenetic relationship of three genera are discussed. The phlogenetic age of the stem species of three genera are estimated at the late Jurassic, based on their phylogenetic relationship and distribution pattern. Two new species, C. noodti and C. teucherti differ from each other in the structure of labrum.
